Data Binding Specification for UI Logic Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The tightly coupled nature of user interface and application logic in computer systems makes code maintenance costly and time-consuming, as changes to the user interface often require modifications to the underlying logic, limiting independence and flexibility in design and development.
Innovation Solution
A system and method that decouples the user interface from the application logic by using a binding specification to associate data with UI properties, allowing independent development and easy updates, with dynamic reflection of data changes and user input, enabling flexible and visually enhanced data presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user interface code and application logic are tightly coupled, then the code can directly manipulate data and update the interface, but the code becomes fragile and costly to maintain when changes are needed
Solution Approach 1:
The patent divides the application into separate components: user interface code and application logic code. The UI code contains only UI-specific statements while application logic code contains data manipulation statements. This segmentation allows independent development and maintenance of each component without affecting the other, directly resolving the fragility issue mentioned in the contradiction.
Solution Approach 2:
The patent extracts application logic from the user interface code by introducing a binding specification that identifies which data items control which UI properties. This extraction separates the concerns of data manipulation and UI presentation, allowing the UI code to remain simple while logic changes can be made independently in the application logic code.
2Productivity
If user interface designers and application authors work independently, then development can proceed in parallel, but they need a mechanism to coordinate their work without understanding each other's code
Solution Approach 1:
The binding specification acts as an intermediary between UI designers and application authors. It provides a standardized interface that defines how data items connect to UI properties without requiring either party to understand the other's code. The binding specification includes syntax for identifying source data items, target UI elements, and the properties they control, enabling independent parallel development.
3Adaptability or versatility
If the user interface needs to be changed to improve user appeal, then the application can adopt new UI platforms, but the application logic must also be changed in traditional systems
Solution Approach 1:
By segmenting UI code from application logic code through the binding specification mechanism, the patent enables independent UI platform changes. The binding specification serves as a stable interface layer that remains unchanged while allowing different UI implementations to connect to the same data sources, thus enabling UI adaptability without logic changes.
4Reliability
If data changes need to be automatically reflected in the user interface, then dynamic updates are required, but this increases the complexity of data binding management
Solution Approach 1:
The binding specification establishes a feedback mechanism where changes in source data items automatically trigger updates to bound UI properties. The system monitors data changes and propagates them through the binding specification to the appropriate UI elements, ensuring data reflection accuracy while automating the management process to reduce complexity.
Data Source
AI summary
Described is a system and method for controlling user interface (UI) properties with data. An application is separated into independent parts, a logic portion and a UI portion. The logic portion manipulates data values within the application. The UI portion is responsible for displaying UI properties. A binding specification describes a relationship between the UI property and the data value. The binding specification is used by system level code to determine the manner in which it is notified when the data value undergoes a change and the manner in which it directs the UI portion to reflect the change in the UI property. The binding specification identifies a source data item, a path to the data value in the source data item, a target UI element, and the UI property on the target UI element. The binding may be specified using code or markup language.
